Q4 2022 Shareholder Letter

2022 was another record year for Airbnb. Revenue of $8.4 billion grew 40% year over year (46% ex-FX). Net income was $1.9 billion—making 2022 our first profitable full year on a GAAP basis. Adjusted EBITDA was $2.9 billion while Free Cash Flow was $3.4 billion, growing 49% year over year.

Guest demand remained strong throughout 2022. All regions saw significant growth in 2022 as guests increasingly crossed borders and returned to cities on Airbnb.

Supply growth was also strong in 2022. We ended the year with 6.6 million global active listings, which is over 900,000 more listings than we had in the beginning of the year, excluding China. This growth was driven by our global network, where demand drives supply, as well as product innovations that continue to attract new Hosts.

Looking forward to 2023, we’re seeing strong demand in Q1, indicating that consumer confidence to travel remains high. This year, we’re focusing on three strategic priorities:

• Make hosting mainstream. If you’re reading this letter, you have likely traveled on Airbnb or know someone who has. We want hosting on Airbnb to be just as popular. To achieve this, we will continue to raise awareness around hosting, make it easier to get started, and provide even better tools for Hosts.

• Perfect the core service. We want people to love our service, and that means obsessing over every detail. Based on feedback from our guests and Hosts, we’re making a large number of upgrades to our service this year—improving community support, making it easier to find the right home for you, delivering greater value, and much more.

• Expand beyond the core. We have some big ideas for where to take Airbnb next, and this year we will build the foundation for future products and services that will provide incremental growth for years to come.

As we continue to innovate and grow, we’re excited to share this journey with you.

Q4 and Full-Year 2022 Financial Results

Here is a snapshot of our Q4 and full-year 2022 results:

• Q4 revenue of $1.9 billion was our highest fourth quarter ever. Revenue grew 24% year-over-year (31% ex-FX) driven by solid growth in Nights and Experiences Booked. For the full year 2022, revenue increased 40% year-over-year (46% ex-FX) to $8.4 billion driven by the increase in demand and Average Daily Rates (“ADR”).

• Q4 net income of $319 million was our most profitable fourth quarter ever. Net income improved by $264 million compared to Q4 2021 primarily due to our revenue growth and expense discipline. In Q4 2022, we delivered a net income margin of 17%, up from 4% in Q4 2021. For the full year 2022, we generated $1.9 billion of net income—our first profitable full year. This compared to a net loss of $352 million for the full year 2021.

3

• Q4 Adjusted EBITDA of $506 million was a record fourth quarter. Adjusted EBITDA in Q4 2022 increased 52% compared to $333 million in Q4 2021. Adjusted EBITDA margin was 27% for Q4 2022, up from 22% in Q4 2021. For the full year 2022, Adjusted EBITDA margin was 35%, compared with 27% for full year 2021. This improvement in Adjusted EBITDA demonstrates the continued strength of our business and discipline in managing our cost structure.¹

• Q4 Free Cash Flow of $455 million was our highest Q4 ever. Q4 2022 net cash provided by operating activities was $463 million, up from $382 million in Q4 2021. The increase in cash flow was driven by revenue growth and net margin expansion. Our FCF for full year 2022 was $3.4 billion, representing a FCF margin of 41%, and year-over-year growth of 49%.² With our Free Cash Flow, we repurchased $1.5 billion of our stock and reduced our fully diluted share count from 703 million at the end of 2021 to 694 million at the end of 2022.

Business Highlights

Our strong quarter was driven by the continuation of a number of positive business trends:

• Guest demand on Airbnb remained strong. Nights and Experiences Booked increased 20% in Q4 2022 compared to a year ago. In Q4 2022, we had our highest number of active bookers yet, demonstrating guests’ excitement to travel on Airbnb despite evolving macroeconomic uncertainties. Globally, we’ve now had 1.4 billion cumulative guest arrivals. And heading into 2023, we see a strong backlog for Q1 with longer lead times for bookings in Q4 2022 compared to a year ago.

• Guests increasingly returned to cities and crossed borders. Cross-border gross nights booked increased 49%, while high-density urban nights booked grew 22% compared to Q4 2021. While the business mix remains different from pre-pandemic levels, we’ve seen consistent growth in both areas. In Q4 2022, high-density urban nights booked was 51% of total gross nights booked (versus 59% in Q4 2019) and cross-border was 44% (versus 47% in Q4 2019). Globally, we saw cross-border travel to all regions increase in Q4 2022 from last year despite continued foreign currency volatility. While Asia Pacific, which has historically been reliant on cross-border travel, has yet to return to 2019 levels, we see China’s recent removal of travel restrictions as an encouraging sign of continued recovery for the region.

• Guests continued to stay longer on Airbnb. Gross nights booked in Q4 2022 for more than a week are 40% higher than Q4 2019. Nights from long-term stays (28 nights or longer) remained stable from a year ago at 21% of total gross nights booked. We’ve seen guests across all regions and age groups use Airbnb for long-term stays.

• Supply on Airbnb grew by over 900,000 active listings. We ended 2022 with 6.6 million active listings—our highest yet. This was an increase of over 900,000 active listings, or 16% compared to 2021, excluding the removal of all mainland China listings in July 2022 based on our decision to close the domestic business in China. Two factors drove this increase in supply. First, demand drives supply. Hosts are attracted to the supplemental income they can earn on Airbnb, which

^{1, 2} A reconciliation of non-GAAP financial measures to the most comparable GAAP measures is provided at the end of this letter.

is often critical during times of inflation and recessionary concerns. Second, our product innovation is having an impact. Over the past two years, we’ve made it more attractive and easier to Host—including our most recent introduction of Airbnb Setup. And we’re not stopping there. We will continuously invest in growing our Host community and helping them succeed.

Results from our 2022 Winter Release

Airbnb Setup

On November 16, 2022, we introduced Airbnb Setup to make it easy for millions of people to Airbnb their home. With Airbnb Setup, prospective Hosts can connect with Superhosts for free one-to-one guidance all the way through their first reservation. Hosts also can choose to host an experienced guest for their first booking and receive specialized support from Airbnb. Since the release and the launch of our “Airbnb It” campaign, the number of visitors to our host landing page has doubled. Since November, the number of new active Hosts recruited with the help of our Superhosts increased more than 20% compared to pre-launch.

AirCover

As part of the Winter Release, we also improved AirCover for Hosts by enhancing guest identity verification, expanding reservation screening, and increasing damage protection to $3 million. For Hosts with an AirCover reimbursement request, the net promoter score has increased nearly 70 points since the introduction.

Airbnb-Friendly Apartments

In Q4 2022, we announced Airbnb-Friendly Apartments, a program that helps long-term renters find apartments that they can host on Airbnb part-time. Renters interested in hosting a spare room, or their entire apartment when they’re out of town, can browse more than 175 Airbnb-friendly apartment buildings in the U.S.—a number that continues to grow. Over the long term, we believe this will help unlock supply in the rental market, which in the past has been largely unavailable.

Total Pricing Display and Tools

We’ve heard from guests that they’d like to view the total price when searching for homes on Airbnb. In response, in December, we rolled out the option for guests to display the total price up-front. When guests opt in, they see the total price before taxes in search results, as well as on the map, price filter, and listing page. Before confirming their booking, guests can still view a full price breakdown with Airbnb’s service fee, discounts, and taxes. Based on the results so far, the business impact has been neutral. We are continuing to iterate and test the pricing display.

In addition to promoting price transparency, we want to ensure our platform offers competitively priced stays. Starting this year, we will provide new and improved pricing and discounting tools to help Hosts understand the final price guests pay and how to set competitive prices. We expect these changes will drive greater affordability and value for guests, support bookings growth, and therefore also help Hosts be more successful. We’re excited to share more with you in the coming months.

The new total pricing option offers guests both the transparency and convenience of seeing the total price of their booking upfront

Meet Fernando. Hosting since 2017 Fernando shares his spacious, airy apartment in central Madrid with private room guests from all over the world.

8

His apartment is a study in meticulous detail. All of his furniture is vintage and the interior celebrates architectural trends of the 20th century. His stylish living room with high ceilings and balconies overlooking the street, contains bold artistic choices to the extent that guests compare his place to boutique hotels. It makes sense for an architect who carefully curates his space.

“My space is very niche,” he said. “People who are very much into the same things I am into (such as design, architecture) really appreciate my house and they leave very positive feedback on that.”

The art on his walls are exhibition posters from different eras with complementary colors. Guests note the elements of Bauhaus design and the mid-century modern movement throughout the space in his reviews.

“In my space, all the furniture and complements are from the 1950s/1970s,” Fernando said. “I’ve always been attracted to those trends, that’s why my house is filled with mixed elements of different schools this period of time. I don’t think of it as decoration. It is my taste for living.”

Fernando began hosting guests at his four-bedroom apartment in 2017, where he lives with his two Spanish greyhounds. He started hosting because people kept marveling at his place, telling him he should list it on Airbnb. Fernando lives and works from his home.

Since he began hosting, one aspect that surprised him most is “how respectful and educated guests are. People are very careful and mindful of my home,” he said.

Fernando receives many international guests from all over the world, including the US, Canada, central Europe, and South America.

“When people from different cultures tell you how they live, what they eat, what their culture is like, sometimes that is very informative and refreshing for me,” he said.

Q4 2022

During Q4 2022, we had 88.2 million Nights and Experiences Booked—our highest fourth quarter ever– representing a significant increase from a year ago (20% Y/Y). While we saw strong growth across all regions compared to Q4 2021, Asia Pacific once again increased the most with 40% more Nights and Experiences Booked.

The combination of the increase in Nights and Experiences Booked, combined with sustained elevated ADR, drove another quarter of strong GBV growth. In Q4 2022, GBV was $13.5 billion, representing a year-over-year increase of 20% (26% ex-FX).

As a result of the strong U.S. dollar in Q4 2022, especially in comparison to the Euro and the British Pound, metrics such as revenue, GBV and ADR, excluding the effects of foreign currency fluctuations, are higher than amounts reported in our financial statements. While we saw Q3 2022 mark a peak of U.S. dollar strength, we saw the Euro and British Pound recoup some lost ground in the latter half of Q4 2022.

Geographic mix

While the trends in our recovery continue to vary by region due to a variety of factors, in Q4 2022, we saw continued strength in all regions relative to the same period in 2021. Meanwhile, global cancellation rates in Q4 2022 remained higher than 2019 levels, but below 2021 levels. We believe we have gained share in global nights stayed relative to both 2019 and 2021. Q4 2022 regional highlights include:

10

• North America remained strong with continued growth in Nights and Experiences Booked. During Q4 2022, revenue earned in the U.S. increased over 19% from Q4 2021 and represented 47% of total global revenue. While the majority of travel in North America, both pre-pandemic and now, is domestic, we saw cross-border Nights and Experiences Booked to North America increase approximately 35% in Q4 2022 compared to the same prior-year period.

• In EMEA, Nights and Experiences Booked grew 25% compared to Q4 2021. The vast majority of European guests on Airbnb travel within Europe, and therefore are not impacted by the strong U.S. dollar.

• In Latin America, Nights and Experiences Booked were 23% higher than Q4 2021, with continued resilience in certain countries, such as Mexico and Brazil.

• In Asia Pacific, Nights and Experiences Booked saw the most significant year-over-year growth primarily due to the continued easing of COVID-19 restrictions that were in place in 2021. This region has historically been reliant on cross-border travel. While still significantly down compared to pre-pandemic periods, we have seen continued sequential recovery in the region, with 40% growth in Nights and Experiences Booked in Q4 2022 compared to a year ago.

• As shared in our Q2 shareholder letter, all mainland Chinese listings were taken down in July 2022 as part of our decision to close the domestic business in China and instead focus on the outbound China business. We are encouraged by China’s recent lifting of its travel restrictions even though we anticipate the outbound recovery to be gradual.

Travel corridors and distance

While domestic and short-distance travel continued to be strong, we saw even further improvement in both longer-distance and cross-border travel during Q4 2022 compared to the prior year. In Q4 2022, guests traveling more than 300 miles increased 25% and cross-border represented 44% of total gross nights booked, up from 34% in Q4 2021.

Urban vs. non-urban

Consistent with recent quarters, we continue to see signs of travelers returning to cities (historically one of the strongest areas of our business). Gross nights booked in high-density urban areas represented 51% of our gross nights booked in Q4 2022.

Trip length

In Q4 2022, long-term stays of 28 days or more accounted for 21% of gross nights booked in Q4 2022, stable with Q4 2021. We anticipate long-term stays to be slightly lower as a percent of total nights in Q1 2023 due to strong growth of short-term stays. Overall, approximately 46% of gross nights booked in Q4 2022 were from stays of at least seven nights.

Average daily rates

ADR was $153 in Q4 2022, representing a 1% decrease from Q4 2021. Excluding the impact of FX, ADR in Q4 2022 increased 5% from Q4 2021. The year-over-year decrease from Q4 2021 was driven by foreign

11

exchange and mix shift as urban destinations and other bookings that tend to have lower ADR rebounded, partially offset by price appreciation. On an FX-neutral basis, Q4 2022 ADR was up across all regions year-over-year.

Supply

In July 2022, all mainland China listings were taken down based on our decision to close the domestic business in China and instead focus on the outbound China business. As such, for comparative purposes, references to supply and supply growth exclude listings in China from prior periods. Active listings grew approximately 16% in Q4 2022 compared to a year ago, representing sequential acceleration relative to Q3 2022. Relative to the end of 2019, we’ve seen global supply grow in-line with global demand. In Q4 2022, total active listings (excluding China) were up 26% and nights booked (excluding China domestic) were up 24%. We saw growth in supply across all market types in Q4 2022 compared to a year ago, including both non-urban and urban supply. We also saw an increase in supply across all regions in Q4 2022 compared to Q4 2021, with the most growth in North America.

In Q4 2022, revenue was $1.9 billion, representing a year-over-year increase of 24% (31% ex-FX). The increase in revenue was driven by the stable growth in Nights and Experiences Booked, which offset a slight year-over-year decline in ADR. As a result of the strength of the U.S. dollar in Q4 2022 relative to Q4 2021, especially in comparison to the Euro and British Pound, metrics such as revenue, GBV and net income, excluding the effects of foreign currency fluctuations, are higher than reported amounts in our financial statements. In Q4 2022, approximately 47% of our GAAP revenue was denominated in non-USD currencies, while a minority of our total costs and expenses were denominated in non-USD currencies.

13

During Q4 2022, the implied take rate (defined as revenue divided by GBV) was 14.1%, which was slightly higher than Q4 2021 primarily due to the timing of when guests booked their travel and when guests stayed.

Operating expenses in Q4 2022 included the impact of $254 million of stock-based compensation expense, which is excluded from Adjusted EBITDA. All recurring operating expense line-items (excluding the impact of stock-based compensation expense) except for general and administrative, increased more slowly year-over-year than revenue, allowing for considerable margin expansion.³ In Q4 2021, general and administrative expense, excluding stock-based compensation expense, incurred lower expenses associated with bad debt and reserves for certain tax and legal matters.

During the height of the pandemic, we made many difficult choices to reduce our spending, making us a leaner and more focused company, and we’ve kept this discipline ever since. Over each of the past two years, we’ve modestly increased our headcount. We ended 2022 with 6,811 employees, and currently expect to continue hiring at a judicious pace in 2023. Compared to 2019, our headcount is down 5% while our revenue is up 75%.

Net income in Q4 2022 was $319 million, a significant increase compared with net income of $55 million in Q4 2021 primarily driven by substantially higher revenue. Relative to Q4 2021, net profit margin increased 13 percentage points (from 4% in Q4 2021 to 17% in Q4 2022).

Adjusted EBITDA for Q4 2022 was $506 million, a significant improvement compared to Adjusted EBITDA of $333 million in Q4 2021.⁴ Our Q4 2022 Adjusted EBITDA demonstrated the continued strength of our revenue recovery and strong ADRs, coupled with our disciplined spending. Relative to Q4 2021, Adjusted EBITDA margin increased 5 percentage points (from 22% in Q4 2021 to 27% in Q4 2022).

Quarterly Revenue ($M)

Q4 2022 revenue of $1.9 billion grew 24% year-over-year.

Quarterly Net Income (Loss) ($M)

2022 was our first profitable full year of $1.9 billion with Q4 2022 net income of $319M.

Quarterly Net Cash Provided by (Used in) Operating Activities ($M)

In 2022, we generated $463 million of net cash provided by operating activities in Q4 and $3.4 billion for the full year.

Quarterly Free Cash Flow ($M)

In 2022, we generated $455 million of Free Cash Flow in Q4 and $3.4 billion for the full year.

Shares (M)

We’re effectively managing share dilution and have repurchased $1.5B of our authorized $2B share buyback program.

Balance Sheet and Cash Flows

For the three months ended December 31, 2022, we reported $463 million of net cash provided by operating activities and $455 million of FCF, compared to $382 million and $378 million, respectively, for the three months ended December 31, 2021.⁵ The year-over-year increase in FCF was driven by revenue growth and margin expansion. For the full year ended December 31, 2022, we generated $3.4 billion of net cash provided by operating activities and $3.4 billion of FCF.

Unearned fees totaled $1.2 billion at the end of Q4 2022, compared to $1.2 billion at the end of Q3 2022 and $904 million at the end of Q4 2021.

As of December 31, 2022, we had $9.6 billion of cash, cash equivalents, marketable securities, and restricted cash. We also had $4.8 billion of funds held on behalf of guests as of December 31, 2022.

In August 2022, we announced that our Board of Directors approved a share repurchase program with authorization to purchase up to $2 billion of our Class A common stock at management’s discretion. In 2022, we repurchased $1.5 billion of our Class A common stock. The share repurchase program will enable us to offset dilution from our employee stock programs.

Outlook

We are excited to see the continued strong demand in Q1 2023. We’re particularly encouraged by European guests booking their summer travel earlier this year, the market share gains we are seeing in Latin America, as well as the continued recovery within Asia Pacific.

We expect revenue of $1.75 billion to $1.82 billion in Q1 2023. This represents year-over-year growth of between 16% and 21% and on an ex-FX basis between 18% and 23%. We expect our implied take rate (defined as revenue divided by GBV) in Q1 2023 to be similar to Q1 2022. We anticipate that the implied take rate seasonality in 2023 will be similar to 2022.

In Q1 2022, travel was significantly impacted by the Omicron strain of COVID-19 in January and to a lesser extent the war in Ukraine during February, making the earlier part of the quarter an easier year-over-year comparison than the end. In Q1 2023, we expect Nights and Experiences Booked year-over-year growth to be nearly as strong as Q4 2022.

In Q1 2023, we anticipate slightly lower ADR than we had in Q1 2022. For the remainder of the year, we expect ADR will face increasing downward pressure from mix shift, as well as new and improved pricing and discounting tools. We will be introducing these tools this year and expect these changes to drive greater affordability and value for guests, support bookings growth, and therefore also help Hosts be more successful.

For the full year 2023, we expect to maintain the strong Adjusted EBITDA margin we delivered in 2022, as we offset the headwinds from lower ADR with incremental variable cost efficiencies and fixed cost discipline. In Q1 2023, we expect Adjusted EBITDA margin to be slightly down on a year-over-year basis due to changes in the timing of our brand marketing spend. Compared to Q1 2022, we expect sales and marketing in Q1 2023 will be approximately 150 basis points higher as a percent of revenue, but flat as a percent of revenue for the full year.

Non-GAAP Financial Measures

In addition to our results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), we review financial measures that are not calculated and presented in accordance with GAAP (“non-GAAP financial measures”). We believe our non-GAAP financial measures are useful in evaluating our operating performance. We use the following non-GAAP financial information, collectively, to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance, and assists in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with GAAP, and may

19

be different from similarly titled non-GAAP measures used by other companies. A reconciliation of each non-GAAP financial measure to the most directly comparable financial measure stated in accordance with GAAP is provided below. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures.

Our non-GAAP financial measures include Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Free Cash Flow Margin, trailing twelve months (“TTM”) Free Cash Flow, TTM Free Cash Flow Margin, revenue change excluding the effect of changes in foreign exchange rates (“ex-FX”), net income ex-FX, net income change ex-FX, Adjusted EBITDA ex-FX, and Adjusted EBITDA change ex-FX.

Adjusted EBITDA is defined as net income or loss adjusted for (i) provision for (benefit from) income taxes; (ii) interest income, interest expense, and other income (expense), net; (iii) depreciation and amortization; (iv) stock-based compensation expense; (v) acquisition-related impacts consisting of gains (losses) recognized on changes in the fair value of contingent consideration arrangements; (vi) net changes to the reserves for lodging taxes for which management believes it is probable that we may be held jointly liable with Hosts for collecting and remitting such taxes; and (vii) restructuring charges.

The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature, or because the amount and timing of these items is unpredictable, not driven by core results of operations and renders comparisons with prior periods and competitors less meaningful. Reconciliations of expected Adjusted EBITDA and Adjusted EBITDA margins to corresponding net income (loss) and net income (loss) margins have not been provided because of the unpredictability of certain of the items excluded from Adjusted EBITDA and because we cannot determine their probable significance. We believe Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations, as well as provides a useful measure for period-to-period comparisons of our business performance. Moreover, we have included Adjusted EBITDA in this letter because it is a key measurement used by our management internally to make operating decisions, including those related to operating expenses, evaluating performance, and performing strategic planning and annual budgeting. Adjusted EBITDA also excludes certain items related to transactional tax matters, for which management believes it is probable that we may be held jointly liable with Hosts in certain jurisdictions.

Adjusted EBITDA has limitations as a financial measure, should be considered as supplemental in nature, and is not meant as a substitute for the related financial information prepared in accordance with GAAP. These limitations include the following:

• Adjusted EBITDA does not reflect interest income (expense) and other income (expense), net, which include loss on extinguishment of debt and unrealized and realized gains and losses on foreign currency exchange, investments, and financial instruments, including the warrants issued in connection with a term loan agreement entered into in April 2020. We amended the anti-dilution feature in the warrant agreements in March 2021. The balance of the warrants of $1.3 billion was reclassified from liability to equity as the amended warrants met the requirements for equity classification and are no longer remeasured at each reporting period;

• Adjusted EBITDA excludes certain recurring, non-cash charges, such as depreciation of property and equipment and amortization of intangible assets, and although these are non-cash

20

charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect all cash requirements for such replacements or for new capital expenditure requirements;

• Adjusted EBITDA excludes stock-based compensation expense, which has been, and will continue to be for the foreseeable future, a significant recurring expense in our business and an important part of our compensation strategy;

• Adjusted EBITDA excludes acquisition-related impacts consisting of gains (losses) recognized on changes in the fair value of contingent consideration arrangements. The contingent consideration, which was in the form of equity, was valued as of the acquisition date and is marked-to-market at each reporting period based on factors including our stock price;

• Adjusted EBITDA does not reflect net changes to reserves for lodging taxes for which management believes it is probable that we may be held jointly liable with Hosts for collecting and remitting such taxes; and

• Adjusted EBITDA does not reflect restructuring charges, which include severance and other employee costs, lease impairments, and contract amendments and terminations.

Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenue. Because of these limitations, you should consider Adjusted EBITDA and Adjusted EBITDA Margin alongside other financial performance measures, including net income (loss) and our other GAAP results.

Free Cash Flow represents net cash provided by (used in) operating activities less purchases of property and equipment. We believe that Free Cash Flow is a meaningful indicator of liquidity that provides information to management and investors about the amount of cash generated from operations that, after purchases of property and equipment, can be used for strategic initiatives, including continuous investment in our business, growth through acquisitions, and strengthening our balance sheet. Our Free Cash Flow is impacted by the timing of GBV because we collect our service fees at the time of booking, which is generally before a stay or experience occurs. Funds held on behalf of our Hosts and guests and amounts payable to our Hosts and guests do not impact Free Cash Flow, except interest earned on these funds. Free Cash Flow Margin is defined as Free Cash Flow divided by revenue. We track our TTM Free Cash Flow to account for the timing difference in when we receive cash from service fees, which is at the time of booking. Free Cash Flow has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by (used in) operating activities. Free Cash Flow does not reflect our ability to meet future contractual commitments and may be calculated differently by other companies in our industry, limiting its usefulness as a comparative measure. TTM Free Cash Flow Margin is defined as TTM Free Cash Flow divided by TTM revenue.

In addition to the actual amount or percentage change, we disclose the amount or percentage change in our current period results for revenue, GBV, net income (loss), Adjusted EBITDA, and ADR from the corresponding prior period results by comparing results using constant currencies. We present constant currency amounts and change rate information to provide a framework for assessing how our revenue, GBV, net income (loss), Adjusted EBITDA, and ADR performed excluding the effect of changes in foreign exchange rates. We use the amounts and percentage change in constant currency revenues, GBV, net

21

income (loss), Adjusted EBITDA, and ADR for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We believe the presentation of results on a constant currency basis in addition to the U.S. GAAP presentation helps improve the ability to understand our performance because it excludes the effects of foreign currency volatility that are not indicative of our core operating results. We calculate the percentage change in constant currency by determining the change in the current period over the prior comparable period where current period foreign currency amounts are translated using the exchange rates of the comparative period.

¹ The condensed consolidated statements of cash flows for the year ended December 31, 2021 has been revised to correct for errors identified by management during the preparation of the financial statements for the three months ended March 31, 2022. The errors understated cash flows from operating activities by $123.0 million and overstated the cash flows from financing activities by $123.0 million for the year ended December 31, 2021. Management has determined that these errors did not result in the previously issued financial statements being materially misstated. These errors primarily related to the timing of tax payments from the net settlement of equity awards at the initial public offering in December 2020. In particular, in 2020, the Company reported $1.7 billion of cash used in financing activities to cover taxes paid related to the net share settlement of its equity awards that vested upon the initial public offering. However, approximately $123.0 million of this amount was actually remitted to taxing authorities in foreign jurisdictions during 2021. This had no impact on the Company’s consolidated financial statements outside of the presentation in the consolidated statements of cash flow and did not affect the consolidated balance sheets, consolidated statements of operations, or consolidated statements of stockholders’ equity.

Gross Booking Value		$11.3B		$13.5B		$46.9B		$63.2B

We track certain key business metrics to measure our performance, identify trends, formulate financial projections, and make strategic decisions. Our key business metrics include GBV and Nights and Experiences Booked. GBV represents the dollar value of bookings on our platform in a period and is inclusive of Host earnings, service fees, cleaning fees, and taxes, net of cancellations and alterations that occurred during that period. Nights and Experiences Booked on our platform in a period represents the sum of the total number of nights booked for stays and the total number of seats booked for experiences, net of cancellations and alterations that occurred in that period. We are not aware of any uniform standards for calculating these key metrics, which may hinder comparability with other companies that may calculate similarly titled metrics in a different way.
